Hello folks,

I'd like to hear your opinions about this topic.

I am looking for an antenna (or more than one) for 10/15/20m that has the
following characteristics:

- vertical polarization
- smallest possible horizontal far field lobe
- "good" forward gain (at least comparing to a single element vertical)
- greatest possible front to back ratio

I was thinking about using:

- a tribander tilted 90 degrees

- 2 element end phased array of:
   - vertical dipoles
   - sitting on the ground verticals (with or without radials?)
   - multiband verticals (using W9AD phasing line to switch between bands)
   - 5/8th wave verticals (at least for 10m, it would be easy to convert CB
antennas)

- a 4 square


These antennas would be used for RX only.

Any suggestions, anecdotal comments, field experiments?

73 and thank for your time,

Felipe Ceglia - PY1NB
